  • 15 minutes: finish a tiny game
  • Day 1: play 9×9
Place one black stone to capture the white stone.

One a day, every day

Today's puzzle.

A small, fresh problem every calendar day. Solve it to extend your streak. Miss a day and the streak resets — so check back tomorrow.

Same puzzle for everyone, anywhere in the world.

Atari first

Reduce the white stones to one liberty (put them in atari). Where do you play?

Black to play

Start with the end in mind

What does winning look like?

Go is a quiet race for empty space. When neither player can gain more, the game ends and you count: each empty point you fully surrounded is a point. Most stones on the board never get captured — they just own land.

  • Stones draw the walls.
  • Empty points inside your wall are your territory.
  • More territory wins. Captures help, but territory decides.

Click Reveal territory on the board to see who won and why.

A finished 9×9 game. Empty points fully surrounded by one color become that color's territory.

Choose your path

Every path starts with placing one stone.
